Patented An". 13, 1918.-

Application filed December 4, 1916. Serial No. 135,015.

In both forms of the invention the inner track' member. 7 shown in my said patent, the outer surface thereof being conical at 8, 9, with the smaller diameter toward the center, the conical surfaces being separated by an, interposed rib is substantiallyof the form '10, the side walls of whichare sloped to cooperate with the similarly shaped grooves in the rollers as hereinafter described. The

rollers difi'er from those of the patented construction substantially only int-he matter of proportions, and in that the central" groove. is formed at its base with a fillet 11. the ends .of the rollers being conical or tapered at 12, 13, and the bases of the conical portions united as shown. 7

So far as described above thetwo forms of the invention illustrated are identical,

and they are also alike in. that theouter track is also formed w th a r b which extends into and coiiperates with the grooves of the rollers. Specifically, however, this outer track is formed differently in, the two modifications In the modification shown in Figs. 1, 2 and the outer track is formed in three sections comprising two annulan end members 1-1, .14, having an inner tapered bearing surface corresponding to the taper -of the. rollers, and an intermediate rib member 15 which, for the purpose of assembling, is formed in two or more sections, which together make a complete annulus cooperating with the grooves in the. rollers. A casing or supporting body 16 is illustrated as formed in two sections 16, 16 screwed together at 17. and provided with internal flanges 18, 1S. overlapping the members 14 and thus holding them in proper relative position. Obviously the casing could be .formcd integral, the flanges being spun over the annular tracks 14 if desired. An {mun-" lar separator or spacing member 19 surrounds the inner member 7 and comprises a. pair of rings 20, 20. spaced apart the length of the rollers and connected by ribs 21 and webs 22. The webs, as shown in Fig. 3. are so tapered that the openings between the same, fit loosely about the rollers which are separately contained therein, and the rings 20, 20 have. an internal diameter which enables them to loosely fit n on the ends of the inner track member The bearing may be assembled by first placing the separator about the inner member 7,

In the modification shownin Figs. 4,5

and (5, the external track member as well asthe internal nfei'nber is integral, and the. conicaltrac'k su'rfa'cesdlfl 14 and the llltelliletll ate nb 15 are formed directly thereon. The
